Epilobium parviflorum, commonly known as Smallflower Hairy Willowherb, is a herbaceous perennial plant belonging to the Onagraceae family.

Etymology

The genus name derives from the Greek words "epi" meaning “upon” and "lobos" meaning “lobe”, with reference to position of the petals above the ovary. The specific Latin name of "parviflorum" means “small flowers”.

Description

The biological form of Epilobium parviflorum is hemicryptophyte scapose,[1] as its overwintering buds are situated just below the soil surface and the floral axis is more or less erect with a few leaves.

Epilobium parviflorum reaches on average 30–80 centimetres (12–31 in) in height.[1] The stem is erect and densely covered with hairs, especially in the lower part. The leaves are opposite, unstalked but not amplexicaul, lanceolate and toothed, rounded at the base, 4–10 centimetres (1.6–3.9 in) long. The tiny flowers are pale pink or pale purple, 6–7 millimetres (0.24–0.28 in) in diameter, with four petals, eight stamens and a 4-lobed stigma. Flowering occurs from June to August.[1] The hermaphroditic flowers are either self-fertilized (autogamy) or pollinated by insects (entomogamy).[2] Fruit is a three-to seven-centimeter long capsule containing very small black seeeds (about 1 mm long), with white fibres that allow the dispersal by wind. This species is quite similar to Epilobium hirsutum, but the flowers are very smaller.[3]

Distribution

This plant occurs in most of Europe, including Britain, from Sweden to Northern Africa and Western Asia up to India, in USA and Canada.[4] [5]

Habitat

It prefers marshes and swamps, moist mountain meadows and slopes, at an average altitude of 0–1,400 metres (0–4,600 ft) above sea level,[1] with a maximum of 2,500 metres (8,200 ft).

Medicinal uses

Extracts of this plant have been used by traditional medicine in disorders of the prostate gland, bladder and kidney, having an antioxidant and antiinflammatory effect .[6][7][8] Extracts of Epilobium have been shown to inhibit proliferation of human prostate cells in-vitro by affecting progression of the cell cycle.[9]
